AUTOMOBILE WHEEL.

Drginal application filed August 9, 1920, Serial No. 402,105. Divided and this application filed December 3, 1925.

rI'his invention relates to improvements in automobile wheels and particularly to wheels having split demountable rims for carrying the tire.

One object of the invent-ion is to provide a simple but effective construction for connecting the ends of a rim of the transplit tyI e 'to hold the ends against radial d isplaccment as well as against circumferential separation. A further object is to form such connecting means for the ends of the rmi substantially integral with the rim ends. In this way, there are no detachable parts which may be lost or which must be manufactured separately and then attached to the rim. By forming such connecting means integrally with the rim they are always hept intact while, at the same time, the cost of the production of the rim is not materially in creased.

This application is a division of applicants co-pending applif` ation Serial No, 402,105, filed August 9, 1920.

wWith these and otliei objects in view, the invention consists incertain novel details of construction and combinations and arrangements of parts all as will be hereinafter more fully described and the novel features thereof particularly pointed out in the appended claims.

In the drawings,-

Figure 1 is a sectional view taken circuinferentially of the rim illustrating one form which the cooperating locking elements may take.

Fig. 2 is a plan view of the inner face of the rim shown in Fig. 1.

Fig. 3 is a sectional view showing a slightly modified form of connecting elements.

Fig. 4 is a view similar to Fig. 2 illustrating the inner face of the rim shown in Fig.

Fig. 5 is a view similar to Fig. 1 illustrating another modified foiin of i'im end locking members.

Fig. G is a. view similar to Figs. 2 and 4 illustrating the rim shown in Fig. 5.

Fig. 7 is a view similar to Fig. l showing a still fui-ther modification of the rim end locking elements.

Fig. 8 is a view similar to Figs. 2, 4 and 6 illustrating the entire face of the rim shown in Fig. 7.

As usual, the rim is adapted to carry a tire, as is Well understood and comprises a Serial No. 72,918.

base portion 10 and outwardly directed tire retaining flanges 11 at the edges of said base portion. To facilitate mounting the tire on the rim, or for removing the tire therefrom, said i'im is split transversely as is well known in the art.

As before generally outlined, the rim ends are preferably locked together against circumferential and radial separation by means formed integrally therewith, each of the rim ends having formed thereon a locking element, the two elements on the two rim ends being adapted to interlock with each other in su: h wise as to prevent such circuinferential or radial separation. If desired, these interlocking elements may be in the form of inwardly directed members formed on the inner face ot' the rim adjacent the split in the latter but, as will become apparent from an examination of the accompanying drawings and from the ensuing description, one of these inwardly directed elements may be dispensed with and one end of the rim provided with an orifice with which the member on the other end of the rim may interlock.

rlie preferred arrangement for locking these ends together, is illustrated in Figs. 1 and 2 wherein one end of the rim is formed with a protruding inwardly extending hook shaped member 14, into which is received projection 15 extending inwardly from the inner face of the rim at a point substantially in line with the split in the rim. lVith this projection 15 and the hook shaped member 14 interlocked, as shown in the drawings, the rim ends are positively held against circumferential separation, these interlocking elements being held in their cooperating locked positions in any suitable way as by a button 1G pivoted to the rim end on which projection 15 is formed and adapted to engage the inner face of the hook shaped member 14. As will be readily appreciated, these interlocking elements may readily be formed integrally with the rim ends without materially increasing the cost of production of the rim and, While such locking members are quite simple in their construction, nevertheless, they are quite effective so far as preventing radial and circumferential separat-ion of the rim ends is concerned.

In Figs. 3 and 4 the hook shaped eX- tension 14'C1 does not protrude beyond the end of the rim on which it is formed but, on the contrary, extends substantially to the end face of that rim end. On the other hand, the inwardly direted projection 15 which cooperates with said hook shaped extension projects beyond the end of the rim on which it is iornicd. These parts, in this modification, function in the same way as in the previous construction and are held in their interlocking positinn by the button 16 as in the construction i'ii'st described.

in the nioditied construction of Figs. 5 and (i, the interlocking,l elements for securing together the rini ends are likewise t'oi'inmt integraliy with the rim but, in this instance, the hook shaped member lli" instead of 'ing' with an inwardly directed e);- ten ion engages in an oritice 15", the end portion of the rim proper being received in the recess of the hook shaped member. Here, again, the locking elements are re tained in their interiori-eil pesitiens Vby the button 16.

in the embodiment et the invention illus4 tinted in Figs. 7 and S the interlocking eiements are formed very much the same in the construction shown in En l and te l 7i, the lic/fik shaped ini Sie? i g beyond the end ot the riin on which it termed and the inwardly directed extension l5C lying substantially in the plaife ot' tir; split in the rim. in this torni of the invention, however, the locking` elements are not disposed radially of the rim but project inwardly at an oblique angle. As in the other forms t the invention, these interlocking elements are maintained in interlocking relatinn by the piveted In considering,` these riin end connecting devices, it should be reinen'lbercd that their principal function is to hold the ends of the rim from radial and circumferential scparation when the rim, carrying an inliated tire,

is removed from the Wheel, as, tor instance, when it is carried as a spare. vWhen the riin, carrying a tire, mounted on a wheel, the telly of the wheel, the rim securing nica and the tire together tend to prevent radial and circinn icrential separation of the riin tnds and thais take :,oine et' the strain from the rini end connecting devices.

ii'hat I claim is:

l. transpiit tire carrying rim divided at one point only, the ends thereof beingl bent to have interlocking engagement to prevent radial displacement, said interlocking' pertions oi the rim being` shaped for engagement with each other to prevent circumferential separation.

ik tire carrying rini divided at one peint nniy, one end having an integral eX- tension which is bent inwardly, the opposite end having` an integral extension which is beni; :si insfnidiy and then outwardly, said extensions being adapted to interlock with each other.

C. it tire caiiying` rim divided at one point oniv, the ends of said rim being provided int-sg; :il extensions bent to form interng hooks, and a hutton pivotcd to one ot ne riin ends and adapted to engage the hcfiked extensions ol' the opposite rim end.

tire carrying rim divided at one point one end having an integral extension inwardiy at one side of the split in i the opposite end havingan integral .fn which tirst bent inwardly and fl i outwardly, the reverseiy-turned eXtenprojecting beyond the split and overlying the iirst mentioned rim cnd and in turned extension thereon to hold the two ends against circumferential and radial separation.
